At the end of 2019, Virtual Reality (VR) and Augmented Reality (AR) were still fairly niche technologies. Even in video games, immersive worlds were not succeeding in enticing the general public, despite the release of major titles dedicated to these platforms, such as Half-Life: Alyx and the hugely popular Pokemon Go. But since the explosion of the Covid-19 pandemic in early 2020, which could impact us for quite a while, things have been evolving. We can now expect an increase in the practical applications of AR and VR in our daily lives, on both personal and professional levels. This is exciting news — which we desperately need in these troubled times.
